Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling, and in particular relates to a geological exploration sampling device. Background Art

[0002] Geological exploration involves surveying and detecting the geology through various means and methods to determine the appropriate bearing layer and foundation bearing capacity, as well as the foundation type and calculation of foundation parameters. To ensure the safety, accuracy, and efficiency of the sampling process, we typically use sampling devices during geological exploration.

[0003] For example, in the prior art, Chinese patent publication number CN108444748A discloses a soil sampling device for farmland pollution control, comprising a top plate, with a left and right upright plates vertically fixed to the bottom of the top plate. The lower ends of the left and right upright plates are both horizontally fixed to a bottom plate, with a rotatable running wheel mounted on the bottom of the bottom plate. A return spring is vertically mounted on the upper surface of the bottom plate, with a lifting plate horizontally connected to the upper end of the return spring. A forward and reverse motor is fixed to the top of the top plate, with a drive shaft coaxially fixed to the output shaft of the forward and reverse motor. The lifting plate is rotatably provided with a sleeve that sleeves around the drive shaft via a bearing. A steel pipe is vertically fixed to the bottom of the lifting plate, with a rotating column located inside the steel pipe and a spiral blade fixed to the surface. Collection boxes are fixed to both sides of the steel pipe, and a feed channel is defined on the upper sidewall of the steel pipe, which communicates with the interior of the collection box. This prior art utilizes the spiral blades to spirally advance upward to convey soil, and then the soil sample is collected by the collection box.

[0004] However, the existing sampling device still has disadvantages. When the above-mentioned existing technology is used for sampling, although soil sampling can be achieved, since the feeding channel port is always in an open state and the rotating column continues to move downward, the soil will continuously enter the collection box through the feeding channel port, causing soil of different depths to enter the collection box, affecting the accuracy of the sample, thereby reducing practicality.

[0058] Specifically, the buffer frame 44 is a multi-layer structure;

[0059] Specifically, the buffer frame 44 includes a first buffer plate and a second buffer plate arranged in sequence from the outside to the inside, and the first buffer plate and the second buffer plate are connected to form an integral structure through a plurality of retaining ribs;

[0060] The buffer frame 44 is used to contact the outside world and to protect the device body 1; the buffer frame 44 can drive the push rod 43 to move, and the push rod 43 can prevent the first elastic member 45 from tilting. At the same time, the buffer frame 44 can squeeze the first elastic member 45 to deform it. The first elastic member 45 and the damping member 46 can buffer the impact of the outside world on the buffer frame 44, thereby improving the protection performance of the device body 1 to prevent the device body 1 from being damaged.

[0061] Specifically, the buffer member includes a push rod 43 and a first elastic member 45 sleeved on the outside of the push rod 43; one end of the push rod 43 is connected to the buffer frame 44, and the other end is slidably connected to the groove 42; the head and tail ends of the first elastic member 45 are respectively connected to the buffer frame 44 and the fixing block 41;

[0068] like Figure 3-5 As shown, the soil sampling operation process of a geological exploration sampling device described in this embodiment is as follows:

[0069] When the first motor 22 is activated, the second magnetic block 63 at the bottom of the sample box 27 is inserted into the placement slot 61. The second magnetic block 63 and the first magnetic block 62 attract each other, securing the sample box 27. Then, the hydraulic cylinder 51 and the first motor 22 are activated. The first motor 22 drives the drill rod 23 to rotate, and the hydraulic cylinder 51 pushes the drill rod 23 downward. The drill rod 23 rotates and drills into the soil. When the drill rod 23 reaches the desired depth, the second motor 33 is activated. The second motor 33 drives the screw 29 to rotate. The rotation of the screw 29 drives the movable frame 31 upward, which in turn drives the sealing plate 32 upward. After the sealing plate 32 moves upward, the entrance of the sample box 27 is exposed. As the drill rod 23 rotates, soil is transported through the sampling port 25 and into the sample box 27.

[0070] After collection is complete, the second motor 33 is started to reverse, causing the sealing plate 32 to return to its original position, sealing the entrance to the sample box 27. The hydraulic cylinder 51 then drives the drill rod 23 and other components to return to their original position. Finally, the sample box 27 is removed from the rack 26, and the sample is taken out, completing a soil sampling operation.

[0071] like Figure 1-3 As shown, the working principle of the protection component described in this embodiment is as follows:

[0072] When an external force strikes the front and rear sides of the device body 1, the buffer frames 44 are configured to directly contact the external force to protect the device body 1. The buffer frames 44 can drive the push rod 43 to move, which can prevent the first elastic member 45 from tilting. Simultaneously, the buffer frames 44 can squeeze the first elastic member 45 to deform it, while the push rod 43 squeezes the second elastic member 73 to deform it. The first elastic member 45, the second elastic member 73, and the damping member 46 can buffer the external force, thereby improving the protection of the device body 1 and preventing damage to the device body 1.

[0073] The above is the working process of the entire geological exploration sampling device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
